There had been astronomical increase in the number of mobile users in recent times. Investigation had shown that these increased numbers of mobile users contribute high percentage of interferences that degrades the Quality of Services (QoS) in wireless network. Hence, interference is the most limiting factor of improved capacity in CDMA cellular network and has been one of the problems militating against the high efficiency of any mobile network. In effect, the scarcity of radio frequency spectrum and the ever increasing network users has necessitated the need to adopt some channel assignment algorithm to achieve acceptable spectrum efficiency.
